The principle for LED panel light

In the late 1970s, the production of monochromatic light-emitting diodes (LEDs) came out and caused a worldwide sensation. This kind of solid-state light source has the advantages of long life, energy saving, easy control of light pollution, high operating reliability, pure luminous color, colorful light color, good controllability, light weight, compact structure, simple power supply, etc., which human beings have understood since Electric light source lighting technology is the first solid electric light source that integrates multiple technical advantages.

The following knowledge points are listed below:

Structure and principle of the LED panel light

The structure of the LED panel light is composed of a backlight module, a light source, a driver, an outer frame structure, and a diffuser plate. The light source is irradiated from two or four sides of the light guide material. The light guide plate processed by the interference pattern allows the light to move in the direction of change. Most of the interfered light is emitted toward the diffuser, and a small part is reflected to the reflective material. The secondary reflection makes the light shine as far as possible to achieve the purpose of lighting.

Flexible design of the LED panel light

LED panel lights are very flexible in the design of the product in the early stage. LED is a point-shaped luminous body. Engineering designers can design various light sources with different shapes and different particles according to customer requirements through the flexible combination of points, lines and surfaces. The LED panel light adopts a uniformly luminous reflective panel and a sealed design, with a high-efficiency light guide plate, and is made of aluminum alloy materials. The luminous effect is uniform and the illuminance is higher.



Advantages of the LED panel light

Firstly, the LED panel light can be used for more than 30,000 hours, which is 5 times that of traditional lighting products. The luminous efficiency is 100lm, the spectrum is narrow, the color rendering is good and the color is solid, which is more convenient for object identification. The LED panel light is easy to install, and the lamp can be directly installed on the lamp without accessories such as rectifiers. Compared with traditional lighting products, the maintenance cost of LED lighting products is extremely low. Modular integrated design can be adopted, and local failures will not affect the normal operation of the entire lamp. The characteristic of the directional light emission of the LED light source is convenient to control the light distribution. It can ensure the ideal lighting effect, eliminate the glare of the LED, greatly improve the utilization rate of the LED light energy and eliminate light pollution. It does not contain pollution elements such as lead and mercury so it does not pollute the environment.


Judging from the phenomena observed in the market, the demand for LED lights has been increasing, especially after the product technology research and development results have been born in recent years, the overall product cost has also fallen to a certain extent. The luminous efficiency has also improved so that LED lights can gradually have the strength to debut in the main lighting field. More and more replaceable bulbs and lamps use LEDs as light sources.

The LED indoor lighting market has huge potential, and various forms of LED lamps have been seen on the market. Whether it is traditional lighting companies or emerging LED companies, they are aiming to replace the big cake of indoor lighting.
